Amazon LEO is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world. Amazon Leo will help close the digital divide by delivering fast, affordable broadband to a wide range of customers, including consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity. About this role We're looking for a Data Scientist to turn data from our satellite fleet into engineering decisions. Every satellite in orbit sends back a steady stream of telemetry. Every unit was also tested heavily on the ground before launch, and the ground segment watches the satellite every day while it operates. Your job is to connect these sources. You'll find out which in-orbit behaviors trace back to what we measured in the factory, which events repeat across the fleet, and which patterns point to weaknesses in the hardware design. Your findings will directly shape how we design, build, test, and operate the next generation of satellites. A typical problem starts small: a handful of satellites show a drifting temperature, an occasional link dropout, or a counter that creeps up faster than expected. You'll work out whether it's a real effect or noise, whether it's spreading, and what the affected units have in common. They might share a manufacturing lot, a configuration, an orbital environment, or a signature in their factory test history. From there you'll form a hypothesis about the physical cause and argue it in front of hardware, firmware, and reliability engineers who will push back hard. You'll also have to say plainly when the data rules your own idea out. Telemetry alone rarely settles the question, so your first stop is the ground test data we already have. Every unit in orbit has a detailed record from manufacturing and environmental testing, and the fleet as a whole is backed by an even larger population of units still on the ground. You'll dig through that history for the same behavior: did the affected units show early signs on the ground, did they sit near a test limit, does the effect appear across many units under certain conditions? Often the answer is already in data no one has looked at in this light. When it isn't, you'll design the ground experiments that can provide it. That means deciding which units to test and under what conditions, how many runs you need before the result means anything, and what outcome would confirm or refute the theory. You'll work with the engineers who run those tests, analyze the results, and close the question with a clear answer and a recommended action. Beyond individual investigations, you'll build the fleet-level view: baselines for healthy behavior, early warning indicators that catch emerging issues before they cause outages, and reliability estimates that tell us how the population is aging. You'll decide which recurring analyses should become automated monitoring and work with software engineers to make that happen. You'll be the person the team turns to when someone asks "is this normal?" about the fleet. The ideal candidate is curious about how hardware fails and comfortable with messy data from many sources. They can turn "we're seeing something odd on a few satellites" into a rigorous analysis and a clear recommendation. What you'll bring: - Master's degree or above in a quantitative field such as statistics, mathematics, data science, physics, electrical or aerospace engineering, or computer science, or PhD - 3/5+ years of hands-on experience in an applied or industry setting using Python and SQL to analyze large datasets such as time series, telemetry, sensor, or test data - Experience applying statistical methods (hypothesis testing, regression, time-series analysis, anomaly detection) to noisy, incomplete real-world data - Experience building visualizations and dashboards that communicate findings to engineers and decision makers - Experience framing and solving loosely defined problems, from the first question to a recommendation people act on - Ability to work with hardware and software engineers and turn their questions into analyses you can actually run Nice to have: - Experience analyzing telemetry from satellites, spacecraft, aircraft, vehicles, or other fleets of deployed hardware - Experience with reliability and failure analysis methods such as survival analysis, Weibull modeling, failure-mode analysis, and root-cause investigation - Familiarity with electronics or RF hardware, manufacturing test, environmental stress screening (thermal cycling, burn-in, HASS/HALT), or yield analysis - Experience with pattern-discovery techniques such as clustering, change-point detection, and unsupervised anomaly detection - Experience with large-scale data tools (Spark, Athena/Presto, Redshift) and AWS - Experience with visualization tools such as QuickSight, Tableau, Grafana, or Plotly/Dash - Experience working with software engineers on data pipelines: data requirements, schema design, data quality checks, and automating recurring analyses - Experience using AI-assisted tools to speed up analysis and automate repetitive work - A track record of changing engineering design or test decisions with data Export Control Requirement Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Key job responsibilities As a Data Scientist, you will… - Analyze in-orbit telemetry to measure the health and performance of satellite subsystems, and detect anomalies and slow degradation early - Correlate in-orbit behavior with pre-launch data, including manufacturing, production test, and environmental test results, to find which ground measurements predict on-orbit performance. Feed those insights back into test limits and screening strategy - Correlate in-orbit data with what the ground segment sees (gateways, customer terminals) and with failure analysis of lab and returned units - Connect events across the fleet by build lot, component, configuration, firmware version, orbit, and operating conditions, so we can tell systemic issues apart from one-off events - Find patterns that point to hardware design weaknesses, measure their impact on the fleet, and present the evidence to hardware engineering teams with clear recommendations - Build visualizations and dashboards that support decisions in fleet health reviews, anomaly investigations, and design reviews - Work with software engineers to improve the data pipeline: define data requirements, improve data quality, link ground and in-orbit datasets, and automate recurring analyses - Own ambiguous investigations end to end, from forming the hypothesis to reporting the outcome to senior engineering leaders About the team Phased Array Antenna System Validation is the team that decides whether a satellite's phased array antennas (PAAs) are ready to fly. These are the electronically steered transmit and receive panels that form the link between the satellite and the ground. We're part of Amazon Leo, Amazon's low Earth orbit satellite constellation, and we own the test strategy, the automation, and the data pipeline that every PAA goes through on its way to orbit. That path runs from early component-level screening through full-panel functional testing and extended environmental stress testing across temperature, vacuum, and vibration. Our responsibility doesn't end at launch. We also own the analysis of telemetry from PAAs in orbit, and we use what the constellation tells us to improve how we test on the ground. We are a hardware-facing software and test team, and we sit where several disciplines meet. Our test automation directs firmware provisioning, self-tests, and environmental profiles on test stations at manufacturing sites. Over a single run it exercises thousands of measurement points: high-speed serial links, clocking, digital beamformer firmware, RF chains, power, and thermal behavior. Every result is tied to a specific serial-numbered part. That builds a detailed, part-level history of how each panel and component behaved under stress, from the factory floor to launch. A large part of our work is investigation. When something fails, we work out whether the cause is the hardware, the firmware, the test equipment, or our own automation, and we decide what should happen next. Over time we have built a growing catalog of failure signatures and their root causes, internal tools for analyzing long-duration tests, and AI-assisted agents that help turn raw logs into conclusions. We care about evidence over assumption. A label on a result isn't the result itself, and a search that finds nothing doesn't prove the problem has no history. Theories get tested against the data before they're accepted. We support multiple hardware generations at once, so the architecture, the questions, and the tooling keep changing. You'll work closely with antenna hardware, firmware, manufacturing, and reliability engineers who are glad to dig into a hard problem with you. Because we own both ends, from the first ground test to behavior in orbit, the loop is closed within the team. What we learn from the constellation goes straight back into our screens, thresholds, and test sequences, so that the next panel we validate is more likely to keep working in orbit.

Amazon Leo is a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband network connectivity to unserved and underserved communities around the world. We are looking for an Applied Scientist to be a founding scientist on the Engineering and R\&D team within Leo Infrastructure and IP Security. The team defends the manufacturing lines, launch sites, and global ground infrastructure behind the constellation from the most sophisticated threat actors on the planet. These requirements create open scientific problems at the intersection of agentic AI, real-time stream processing, graph-based reasoning, and behavioral analytics. You will build the science behind a neurosymbolic reasoning platform and the models that detect the behavior of sophisticated threat actors. This is an R\&D role with a production mandate, where you define the problem rather than solve a pre-scoped one, and every model, detection, and agent workflow you build becomes the system Leo's security teams use to protect the constellation. #### Export Control Requirement Due to applicable export control laws and regulations, candidates must be a U.S. citizen. Key job responsibilities - Design and implement scalable, production-grade neurosymbolic systems that integrate symbolic reasoning over graph-based knowledge representations with LLM agents to deliver reliable, verifiable security outcomes. - Design and run reinforcement learning and fine-tuning pipelines (GRPO, PPO, DPO) to optimize language models for security reasoning, triage, and detection-authoring tasks. - Build behavioral and statistical models that detect threat actor behavior, and design the evaluation frameworks that measure model performance against that behavior before trusting a model in production. - Design and build multi-agent systems that autonomously triage, enrich, and contain security events, including the constrained reasoning, safety guardrails, and validation mechanisms that make automated decisions trustworthy at scale. - Own the end-to-end science lifecycle, from research and experimentation through production deployment, defining the metrics that measure system performance and real-world security impact. - Advance the state of the art through publications at top-tier venues, patents, or open-source contributions, and shape the scientific agenda and research culture from day one. A day in the life You will move between research and production in the same week: framing an ambiguous security problem as a scientific question, prototyping an approach, and partnering with software engineers to ship it as a capability the platform runs continuously. Security engineers on your team translate threat intelligence into the adversary behaviors that matter; you build the models that detect those behaviors and evaluate model performance against them. You will obsess over the two latencies that define the platforms, the time from event to detection and the time from detection to containment action, and design agents and detections that drive both down. You will backtest candidate detections against retained telemetry, review evaluation results before a model or agent capability graduates to automated execution, and deliver scientific artifacts that ship. About the team Leo Infrastructure and IP Security protects the people, facilities, hardware, and supply chain behind a global satellite constellation. The Engineering and R&D team within this organization builds the platforms and tooling the security pillar teams operate on, moving security operations from manual triage to correlation-based detection, automated response, and agentic AI. The team is composed of applied scientists, software engineers, and security engineers working across physical and digital security domains. #### Inclusive Team Culture In Amazon Security, it's in our nature to learn and be curious. Ongoing DEI events and learning experiences inspire us to continue learning and to embrace our uniqueness. Addressing the toughest security challenges requires that we seek out and celebrate a diversity of ideas, perspectives, and voices. #### Training & Career Growth We're continuously raising our performance bar as we strive to become Earth's Best Employer. That's why you'll find endless knowledge-sharing, training, and other career-advancing resources here to help you develop into a better-rounded professional. #### Work/Life Balance We value work-life harmony. Achieving success at work should never come at the expense of sacrifices at home, which is why flexible work hours and arrangements are part of our culture. When we feel supported in the workplace and at home, there's nothing we can't achieve.
